I have a 1x1x1 cyst and a 7x5 nodule on my thyroid. I believe they are not supposed to be there, so may be causing an issue. I am vegan, bike 8-12 miles a day, lift, do a video workout(Jillian) train for 1/2 marathons(walk) but my weight does not budge, nor the inches. My THS has gone from 2.1 to 3.78 in the last 1-2 years. In Canada they will do nothing until it reaches 10. Now what do I do?
